Radical feminism is a "current"[1] within feminism that focuses on the theory of patriarchy as a system of power that organizes society into a complex of relationships based on an assumption of "male supremacy"[1] used to oppress women. Radical feminism aims to challenge and to overthrow patriarchy by opposing standard gender roles and the male oppression of women, and calls for a radical reordering of society. Early radical feminism, arising within second-wave feminism in the 1960s,[2] typically viewed patriarchy as a "transhistorical phenomenon"[3] prior to or deeper than other sources of oppression, "not only the oldest and most universal form of domination but the primary form" and the model for all others.[4] Later politics derived from radical feminism ranged from cultural feminism[1] to more syncretic politics that placed issues of class, economics, etc. on a par with patriarchy as sources of oppression.[5]
